I've been having very frequent heart palpitations (at least thats what I think they are). Its like a flutter in my chest... doesn't hurt, but it definitely catches my attention. They happen every so often (maybe a few times a week for the past couple months) and i've never thought anything of it. Tonight, it's been going on roughly every 2-3 minutes for the past hour. Its starting to hurt a little.

Any idea whats going on? should I be worried? I'm sick, just getting over a cold, but I don't think that has anything to do with it. I just need some suggestions.
